En esta guía, se describe cómo integrar opiniones en la app con Kotlin o Java. Hay guías de integración separadas si usas código nativo, Unity o Unreal Engine.
Cómo configurar tu entorno de desarrollo
La biblioteca de Play In-App Review forma parte de las bibliotecas de Google Play Core.
Incluye la siguiente dependencia de Gradle para integrar la biblioteca de Play In-App Review.
Groovy
// In your app's build.gradle file:...dependencies{// This dependency is downloaded from the Google's Maven repository.// So, make sure you also include that repository in your project's build.gradle file.implementation'com.google.android.play:review:2.0.2'// For Kotlin users also add the Kotlin extensions library for Play In-App Review:implementation'com.google.android.play:review-ktx:2.0.2'...}
Kotlin
// In your app's build.gradle.kts file:...dependencies{// This dependency is downloaded from the Google's Maven repository.// So, make sure you also include that repository in your project's build.gradle file.implementation("com.google.android.play:review:2.0.2")// For Kotlin users also import the Kotlin extensions library for Play In-App Review:implementation("com.google.android.play:review-ktx:2.0.2")...}
Cómo crear el ReviewManager
El objeto ReviewManager es la interfaz que permite que tu app inicie un flujo de opiniones integradas en la app. Para obtenerlo, crea una instancia con ReviewManagerFactory.
Sigue las instrucciones sobre cuándo solicitar opiniones integradas en la app para determinar buenos puntos en el flujo de usuarios de tu app para solicitarles que brinden una opinión (por ejemplo, cuando completan un nivel en un juego). Cuando tu app alcance uno de estos puntos, usa la instancia de ReviewManager para crear una tarea de solicitud. Si se ejecuta de forma correcta, la API devuelve el objeto ReviewInfo necesario para iniciar el flujo de opiniones integradas en la app.
Kotlin
valrequest=manager.requestReviewFlow()request.addOnCompleteListener{task->if(task.isSuccessful){// We got the ReviewInfo objectvalreviewInfo=task.result}else{// There was some problem, log or handle the error code.@ReviewErrorCodevalreviewErrorCode=(task.getException()asReviewException).errorCode}}
Java
ReviewManagermanager=ReviewManagerFactory.create(this);Task<ReviewInfo>request=manager.requestReviewFlow();request.addOnCompleteListener(task->{if(task.isSuccessful()){// We can get the ReviewInfo objectReviewInforeviewInfo=task.getResult();}else{// There was some problem, log or handle the error code.@ReviewErrorCodeintreviewErrorCode=((ReviewException)task.getException()).getErrorCode();}});
Cómo iniciar el flujo de opiniones integradas en la app
Usa la instancia ReviewInfo para iniciar el flujo de opiniones integradas en la app. Espera hasta que el usuario complete el flujo de opiniones en la app antes de que esta continúe su flujo normal de usuarios (por ejemplo, avanzar al siguiente nivel).
Kotlin
valflow=manager.launchReviewFlow(activity,reviewInfo)flow.addOnCompleteListener{_->// The flow has finished. The API does not indicate whether the user// reviewed or not, or even whether the review dialog was shown. Thus, no// matter the result, we continue our app flow.}
Java
Task<Void>flow=manager.launchReviewFlow(activity,reviewInfo);flow.addOnCompleteListener(task->{// The flow has finished. The API does not indicate whether the user// reviewed or not, or even whether the review dialog was shown. Thus, no// matter the result, we continue our app flow.});

There are separate integration guides if you are using [native\ncode](/guide/playcore/in-app-review/native), [Unity](/guide/playcore/in-app-review/unity) or [Unreal Engine](/guide/playcore/in-app-review/unreal-engine).\n\nSet up your development environment\n\nThe Play In-App Review Library is a part of the [Google Play Core libraries](/guide/playcore).\nInclude the following Gradle dependency to integrate the Play In-App Review\nLibrary. \n\nGroovy \n\n```groovy\n// In your app's build.gradle file:\n...\ndependencies {\n // This dependency is downloaded from the /studio/build/dependencies#google-maven.\n // So, make sure you also include that repository in your project's build.gradle file.\n implementation 'com.google.android.play:review:2.0.2'\n\n // For Kotlin users also add the Kotlin extensions library for Play In-App Review:\n implementation 'com.google.android.play:review-ktx:2.0.2'\n ...\n}\n```\n\nKotlin \n\n```kotlin\n// In your app's build.gradle.kts file:\n...\ndependencies {\n // This dependency is downloaded from the /studio/build/dependencies#google-maven.\n // So, make sure you also include that repository in your project's build.gradle file.\n implementation(\"com.google.android.play:review:2.0.2\")\n\n // For Kotlin users also import the Kotlin extensions library for Play In-App Review:\n implementation(\"com.google.android.play:review-ktx:2.0.2\")\n ...\n}\n```\n\nCreate the ReviewManager\n\nThe [`ReviewManager`](/reference/com/google/android/play/core/review/ReviewManager) is the interface that lets your app start an in-app\nreview flow. Obtain it by creating an instance using the\n[`ReviewManagerFactory`](/reference/com/google/android/play/core/review/ReviewManagerFactory). \n\nKotlin \n\n```kotlin\nval manager = ReviewManagerFactory.create(context)\n```\n\nJava \n\n```java\nReviewManager manager = ReviewManagerFactory.create(context)\n```\n\nRequest a ReviewInfo object\n\nFollow the guidance about [when to request in-app reviews](/guide/playcore/in-app-review#when-to-request) to determine good\npoints in your app's user flow to prompt the user for a review (for example,\nwhen the user completes a level in a game). When your app reaches one of these\npoints, use the [`ReviewManager`](/reference/com/google/android/play/core/review/ReviewManager) instance to create a request task. If\nsuccessful, the API returns the [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) object needed to start the\nin-app review flow. \n\nKotlin \n\n```kotlin\nval request = manager.requestReviewFlow()\nrequest.addOnCompleteListener { task -\u003e\n if (task.isSuccessful) {\n // We got the ReviewInfo object\n val reviewInfo = task.result\n } else {\n // There was some problem, log or handle the error code.\n @ReviewErrorCode val reviewErrorCode = (task.getException() as ReviewException).errorCode\n }\n}\n```\n\nJava \n\n```java\nReviewManager manager = ReviewManagerFactory.create(this);\nTask\u003cReviewInfo\u003e request = manager.requestReviewFlow();\nrequest.addOnCompleteListener(task -\u003e {\n if (task.isSuccessful()) {\n // We can get the ReviewInfo object\n ReviewInfo reviewInfo = task.getResult();\n } else {\n // There was some problem, log or handle the error code.\n @ReviewErrorCode int reviewErrorCode = ((ReviewException) task.getException()).getErrorCode();\n }\n});\n```\n| **Note:** The [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) object is only valid for a limited amount of time. Your app should request a `ReviewInfo` object ahead of time (pre-cache) but only once you are certain that your app will launch the in-app review flow.\n\nLaunch the in-app review flow\n\nUse the [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) instance to launch the in-app review flow. Wait until\nthe user has completed the in-app review flow before your app continues its\nnormal user flow (such as advancing to the next level). \n\nKotlin \n\n```kotlin\nval flow = manager.launchReviewFlow(activity, reviewInfo)\nflow.addOnCompleteListener { _ -\u003e\n // The flow has finished. The API does not indicate whether the user\n // reviewed or not, or even whether the review dialog was shown. Thus, no\n // matter the result, we continue our app flow.\n}\n```\n\nJava \n\n```java\nTask\u003cVoid\u003e flow = manager.launchReviewFlow(activity, reviewInfo);\nflow.addOnCompleteListener(task -\u003e {\n // The flow has finished. The API does not indicate whether the user\n // reviewed or not, or even whether the review dialog was shown. Thus, no\n // matter the result, we continue our app flow.\n});\n```\n| **Important:** If an error occurs during the in-app review flow, do not inform the user or change your app's normal user flow. Continue your app's normal user flow after `onComplete` is called.\n\nNext steps\n\n[Test your app's in-app review flow](/guide/playcore/in-app-review/test) to verify that your integration is\nworking correctly."]]
